My invention relates to improvements in weed killers of the variety wherein a fluid such as gasoline is utilized in destroying weeds by injecting it into the roots thereof.

I The objects of the invention, stated in a general way, are: r j

To provide a device of this character in which the usual built-in container for" said fluid is eliminated, the container in this de- 10 vice consisting of an ordinary glass bottle such as is found in every household or which may be easily supplied by the user, with the result that the devicemay bemarketed without a container for the fluid, thereby simvl5 plifying such a device,'reducing its cost of manufacture, and lessening its-weight and bulk; I

To afford instrumentalities, including valve mechanism, associated with said' bottle,

1 and means for supporting the instrumentalities and bottle in place, whereby the root of a plantmay be crushed and a definite quantity of'said fluid may be released from the bottle and conveyed into said root'at one operation; and,

I complete,said bottle having. been installed therein. i i

Fig. 2 is a vertical section of a valve member mounted over the neck of said bottle, the bottle being sectionized and broken away, a supporting rod for said member and bottle 40 also being shown, the same appearing partly in section and broken away.v I Fig. 3 is a cross section drawn on the line 3-3 of Fig. 2', illustrating said rod more in detail and particularly its angularly disposed and bifurcated end portion as it contacts with said member, also a spindle installed in the member and an air vent {for the bottle extending through the member, Y

Referring more particularly to the draw- 1750 ing, 1 denotes the bottle heretofore referred to. Said valve'member comprises a hollow base portion2 adapted to fit over the neck of an ordinary bottle, a rubber gasket? being provided to. give it a leak-tight connection therewith 4 denotes a'tube secured in said base portion, one end extending through the outer periphery of said portion andthe other end extending within the bottle to apoint adjacent the bottom thereof, to afford an air vent for the bottle. "The inner end ofthe tube is so located as to prevent leakageunder usual conditions, but to render leakage unllkely at all, the caliber of the tube is preferably small, or said end may be further restricted in size, if.desired. A lug 5 is disposed onopposite sides of said base portion, the samebeingdesigned to prevent lateral displacement of the bifurcatedend of said rod, as will hereinafter more particularlyappear. F Surm'ounting said base portion-is an elongated portion 6 having albo're-like opening? which extends for'the' major portion' of its length and constitutes'a valve chamber. "Said opening'alsoextends through said base pQr- 175 tion and here it isiinteriorly threaded, as at 8, to accommodate a member thre'adedl'y'engaged therewithjwhich serves as aivalve seat and ifs provided with an outlet port 10 for the bottle, said v port communicating with the chamber 7s 11 designatesa bore-like opening commun' i'cating with the chamber 7 andezitending through the 'outer end of saidpo'rtion 6, this second opening beingof lesser diameter than the said chamber but in aXialalignment therewith shoulder is thereby formed at the junction of the opening 11- with the chamber 7, said shoulder being denotedas 12.. This" shoulder, as it will-be seen presently, functions as 'avalve seat as one of "its I duties. I I

A valve spindle, generally denoted as;13,

is mounted in'the'ch-amber 7 and opening 11, the same having a circumferential projection 14: which is normally seated on the shoulder 12. Thisprojection is'circular in outline, and as it may-benotedin Fig'. 2, is'of a diameter slightlyless than theJchamber Z. A spiral spring 15 is'disposed'around the inner end of saidi spindle and is mounted under com-.

naeacaa 4. In a weed killer wherein an ordinary bottle is utilized as a container for a weedkilling fluid; instrumentalities adapted to be packaged in a compact knock-down condition, comprising a root-crushing and liquiddispensing device adapted to be detachably mounted over the mouth of the bottle, a lightweight compactable supporting and handle member, and means whereby said bottle in an inverted position and with said device installed thereon may be detachably secured to said member.

5. A weed killer, comprising an assembly of a bottle and a root-crushing and liquiddispensing device fitted over the mouth of the bottle, a supporting rod for said assembly carrying at one end a clamping jaw for engaging and retaining said device on the bottle and positioning said assembly relative to said rod, and means cooperating with the clamping j aw for securing the rod to the bottom of the bottle and operatively securing said assembly in place.
